Hypoxia in Marine Ecosystems: Implications for Neritic Copepods
http://www.planktoneer.com/research.html#HYPOX
Hypoxia in Marine Ecosystems: Implications for Neritic Copepods
<p><em>Description from NSF award abstract:</em><br />The occurrence of low-oxygen waters, often called "dead zones" in coastal ecosystems throughout the world is increasing. Despite these increases, the pelagic food-web consequences of low-oxygen waters remain poorly understood. Laboratory research has demonstrated that hypoxic water (< 2 mg l-1) can result in mortality, reduced fitness and lower egg production of planktonic copepods, a major link in food webs supporting pelagic fish. Observations in the sea indicate that hypoxic bottom waters usually have depressed abundances of copepods compared to normoxic waters (> 2 mg l-1). The gradient of declining oxygen concentration with respect to depth (oxycline) can be a critical interface in coastal pelagic ecosystems by altering the migratory behavior and depth distribution of copepods and their spatial coherence with potential predators and prey. This project will result in a mechanistic understanding of how behavior and fitness of copepods are affected by hypoxia. The PIs will compare bottom-up and top-down controls on the ecology of copepods in Chesapeake Bay waters experiencing seasonal hypoxia and those that are normoxic.</p><p>Specific objectives of this project are to:<br />1) analyze changes in migratory behavior and fine-scale (meter) distribution of copepods across the oxycline over hourly and diel time scales while simultaneously examining the distribution and abundance of their food (phytoplankton and microzooplankton) and predators (fish, gelatinous zooplankton);<br />2) estimate effects of hypoxia on the "fitness" of copepods using a suite of measurements (length/weight ratios, feeding, egg production, and egg hatching success) to develop condition indices of copepods captured at different times and depths in hypoxic and normoxic waters; and<br />3) evaluate effects of hypoxia on copepod mortality by hypoxia-induced, stage-specific copepod mortality in hypoxic bottom waters and by changes in top-down control of copepods from predation by fish and gelatinous zooplankton.</p><p>Oxyclines may be a barrier to vertical migration of copepods and thus disruptive to predator avoidance behavior. Faced with increased predation risk from fish and jellyfish, copepods may seek refuge in hypoxic waters for part of the day and/or make short-term vertical excursions between hypoxic and normoxic waters. By regulating vertical migrations, copepods may increase utilization of microzooplankton prey concentrated in the oxycline. Hypoxic waters may elevate consumption of copepods by jellyfish and depress consumption by pelagic fish. This project will evaluate copepod distribution and migration behavior, individual fitness and stage-specific mortality in hypoxic and normoxic waters. It will examine food-web consequences of increased or decreased spatial coherence of copepods and their predators and prey in regions with hypoxic bottom waters and will contribute to fundamental understanding of food-web processes in eutrophic coastal ecosystems.</p><p>Project acronym "DeZoZoo" = "Dead Zone Zooplankton"</p>

PI-supplied Description: Depth in saltwater; General Description: Observation/sample depth below the sea surface. Units often reported as: meters, feet.When used in a JGOFS/GLOBEC dataset the depth is a best estimate; usually but not always calculated from pressure; calculated either from CTD pressure using Fofonoff and Millard (1982; UNESCO Tech Paper #44) algorithm adjusted for 1980 equation of state for seawater (EOS80) or simply equivalent to nominal depth as recorded during sampling if CTD pressure was unavailable. NERC Description: The distance of a sensor or sampling point below the sea surface.

temp_diff
water temperature
PI-supplied Description: Temperature difference calculated between different temperature sensors; General Description: water temperature at measurement depth NERC Description: The degree of hotness at any position within a volume of fresh or salt water expressed against the International Temperature Scale 1990 (ITS-90) calibration standard.

C
sal
salinity calculated from CTD primary sensors
PI-supplied Description: Salinity from sensor 1; General Description: salinity, calculated from the CTD 'primary sensors' of conductivity and temperature, Practical Salinity Scale (PSS-78), dimensionless. Depending on the input source, salinity from the primary sensors can have a variety of names i.e. s0, s00, sal0, sal00. NERC Description: This is the preferred term for this definition. Alternative term PSALST02 is included to cover cases where there are two sensors of the same type contributing to the data set and referential integrity considerations prevent a usage of a single code.

sal2
salinity calculated from the CTD secondary sensors
PI-supplied Description: Salinity from sensor 2; General Description: salinity, calculated from the CTD 'secondary sensors' of conductivity and temperature, Practical Salinity Scale, dimensionless. Depending on the input source, salinity from the secondary sensors can have a variety of names including s1, s2, s11, s22, sal1, sal2, sal22, sal_S.

n/a
density_diff
sigma-t
PI-supplied Description: Density difference between the primary and secondary sensors.; General Description: Sigma-t density, in kg/m^3 - 1000. 'Sigma-t' is density minus 1000 (without the effect of pressure). It is normally calculated from observations of temperature and salinity. (See How do we measure the density of sea water?) NERC Description: Computed by UNESCO SVAN function using in-situ temperature

CTD
CTD
PI Supplied Instrument Name: CTD PI Supplied Instrument Description:Standard CTD911+ with fluorometer and oxygen sensors working. Instrument Name: CTD Sea-Bird 911 Instrument Short Name:CTD SBE 911 Instrument Description: The Sea-Bird SBE 911 is a type of CTD instrument package. The SBE 911 includes the SBE 9 Underwater Unit and the SBE 11 Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.).
